CiM Fremen is a brilliant sky blue opaque colour that is brighter and happier than Effetre Dark Sky Blue, and bluer than Effetre turquoise. I find the colour of Fremen sort of overwhelmingly bright on its own (like the startlingly blue eyes of the Fremen people in the book "Dune" by Frank Herbert!), but love it when it is combined with other colours.

Here you can see that Fremen turns brick red when you reduce it. This is a common characteristic of colours that contain a lot of copper.

On top of Fremen, silver gets a greyish/beigeish look to it which is lacy and shows up fairly solidly against the base colour. If you reduce and encase this reaction, most of the interesting variation is lost and for some reason, the silver turns a strange ochre yellow colour.

Here you can see that Fremen is 'meh' with silver glass.

On top of Peace, Fremen looks almost fluorescent, it is so bright. I'm not sure why this is, but it is a very dramatic difference from how Fremen looks on top of other colours. It also seems to bleed into the Peace a bit, which you can see on both beads. The Peace lines on top of Fremen look almost light blue rather than white, and separate slightly.

As you might expect, Fremen and Ivory have a reciprocal dark line reaction. This reaction is sort of spready, and the more you heat these two colours together, the bigger, messier, and more pronounced it gets.

I didn't get much of a reaction when I used Fremen on top of Opal Yellow, but my Opal Yellow struck a pretty pink colour in a number of places where I used it on top of Fremen. It could just be that it was a particularly pinkish Opal Yellow, but I try not to use my nice pink Opal Yellow when I make test beads, so it could also be Fremen-related.

Copper Green and Fremen both separate when used together, with the reaction being visible in the colour that is used on top. I'm not sure how useful this knowledge is since in my opinion these colours don't look all that nice together, but you may feel differently.

Fremen separates on top of Tuxedo. Tuxedo looks more or less inert, whether Fremen is on top of it or underneath it.

This goddess bead was made with Fremen and one my 104 CoE frit blends, Ode to Blues.

All of these beads have Fremen in them. The first two sets are Spanish Leather + Ivory + Fremen.

These ones are Tuxedo with a design using wigwag cane that included Fremen.

And these also have Fremen in them, combined with a couple of other colours.

About the Reaction Index

This index of reactions, or 'neat effects', is a work in process, and organizes the reactions I have observed in my test beads. I do not claim to have 'invented' any of these reactions, nor do I consider myself any kind of authority on glass reactions. In many cases, I have made up names that suit me to describe the reactions, and I'll continue to do that unless I happen to learn what it is supposed to be called.

I am a student of glass, and am taking a fairly scientific approach to my relationship with it. The results of that experimentation are here as a reference for anyone who is interested.
